This is my self built 3d printer, it started off as an Ultimaker original but since originally building it in 2012 its had over 3 years worth of changes so the only thing that has really stayed since the beginning is the frame. I built it from scratch using the open source files as a base to start from.
I heavily modified the frame before laser cutting it from 5mm Acrylic, adding direct drive motor mounts and custom connector holes. I have designed and build a number of concept hot end mounts which have gone through a number of revisions. I started by machining my own hot end from aluminium and PEEK before commercial hot ends were available.
Next I used the J-Head IV which required a custom mounting system, I machined an aluminium block to mount the XY linear bearings and a clamp to secure the hot end. This block also incorporated places to mount a proximity sensor for auto bed levelling and a cooling fan.
The most recent iteration of the hot end assembly is the change of hot end to an E3D V6 which utilises an all metal construction.
